I thought that the maximum force on the block in the x direction would be the point where the ball crosses the plane of center and thus frictional force would be maximum, and if the block does not slip in that case then it never will slip as the value of force in x direction only decreases...

the orbit would flatten more and the closest approach to the sun would be very near

undergraduate/ secondary school and I got this problem from a question bank. Can you explain the second method?

i am not sure about this. i know that t^2 is directly proportionl to the cube of semi major axis

TL;DR Summary: if a planet was suddenly stopped in its orbit, suppose to be circular, find how much time will it take in falling onto the sun(in terms of time period) I know that T=2pi (r^3/GM)^1/2 and a=GM/x^2 how to proceed further
